Mood swings are the most common symptom of bipolar disorder and are a combination of the manic and depressive symptoms. A mood swing is characterized by high levels of positivity followed by high levels of negativity and depression or vice versa. Manic periods can last anywhere from a few days to a few months, as can their depressive counterparts.

Many people with bipolar disorder also experience a buffer phase known as “hypomania.”These are like mild manic episodes which do not significantly interfere with the patient’s everyday responsibilities and behavior. It is also common for people to experience mood instabilities in the days leading up to the full onset of a manic or depressive episode.

2. EuphoriaType: Manic

A manic episode will present symptoms of euphoria in patients. Sufferers experience aheightened level of happiness and a sense of accomplishment. They often engage ingoal-oriented projects and activities, and feel “unstoppable” in the pursuit of these goals, even though they are often easily distracted from them.

Some patients describe the euphoria of bipolar disorder as a kind of “high.” They may feel very outgoing and unnaturally happy regardless of whether or not the social situation they are in warrants it. Conversely, the euphoria can suddenly give way to extreme irritability.

3. Rapid SpeechType: Manic

A good indication that someone is experiencing a manic episode is rapid speech. Patients will suddenly begin speaking extremely quickly for long periods of time, but they are rarelyable to follow a train of thought through to its logical conclusion. Instead, they tend to jump from one subject to another in rapid-fire mode, displaying thought patterns that make little sense to others around them.

The rapid speech symptoms are part and parcel of a general burst of energy which patients experience during a manic episode. Other characteristics include a sudden increase in pursuing goal-oriented activities and a feeling of being “unstoppable.” Restlessness and an overestimation of one’s own abilities are also hallmarks of the energy burst symptom.

4. Racing ThoughtsType: Manic

Racing thoughts are a common manic bipolar symptom. Individuals will often have a difficult time focusing on one thing and will tend to over-analyze their thoughts. Thoughts and speech jump seemingly at random from one unrelated topic to another, which increases the patient’s distractibility. Such symptoms significantly hold back the patient’s pursuit of goal-oriented objectives.

During milder manic episodes known as “hypomania,” patients are largely able to curtail the chaotic consequences of their racing thoughts. While patients may enjoy clarity of mind and high periods of productivity during the hypomania phase, these positive effects suddenly vanish when the patient descends into full-on mania.

5. IrritationType: Manic and Depressive

Irritation and agitation are common in both manic and depressive episodes. Sufferers are easily irritated by situations they normally wouldn’t be agitated with. Mood instabilities are typically present during both manic and depressive episodes; patients may quickly switch from one extreme to the other before returning to their euphoric or despondent baseline.

Treatment for bipolar disorder often focuses on stabilizing mood, thus preventing both sudden and longer-phase shifts between happiness and sadness. The severity of mood swings are often used by clinicians to determine how well a given patient is (or is not) responding to treatment.

6. Increased Physical ActivityType: Manic

When a person is experiencing a manic episode they will often have extremely high levels of energy. To help relieve the energy, sufferers often turn to physical activity. If someone suddenly feels the need to exercise excessively to exert energy, it may be an indication of an underlying problem if it continues in a cyclical pattern and is interrupted by long periods of lethargy.

Another way in which this symptom manifests is through compulsive sexual behavior. During a manic episode, a patient may suddenly engage in risky or excessive sex with little to no regard for possible consequences. This can lead to a whole host of other issues, including STIs and unwanted pregnancies.

7. Careless Use of Drugs/AlcoholType: Manic

Sometimes, people suffering from bipolar disorder will turn to drugs and alcohol. Careless use of these substances may be a warning sign of deeper issues. Worse, illicit drugs and excessive alcohol consumption have both been shown to further destabilize mood, which just makes the condition’s symptoms all that much worse.

Drugs and alcohol are also known to increase the anxiety that can accompany the hypomanic “bridge phase.” It’s little wonder that most successful treatment programs stress to patients that they must limit or eliminate alcohol consumption and avoid street drugs altogether.

8. Decreased Need for SleepType: Manic

As previously noted, manic episodes often involve large bursts of energy and euphoria. These symptoms can make it incredibly difficult to sleep. An individual experiencing this symptom may require less sleep, but won’t necessarily feel tired or exhausted. Thus, this symptom is often mischaracterized as insomnia.

A person suffering from insomnia experiences persistent difficulty falling asleep or staying asleep. This isn’t quite what happens during a manic episode. Patients typically just don’t feel tired to the same degree they normally would, and as such, they choose to stay up and use outlets to expend their energy rather than try to sleep.

9. Missed WorkType: Manic and Depressive

A common symptom of bipolar disorder is the inability to maintain a schedule. For this reason, many bipolar sufferers will often miss work (or school or other commitments). In fact, one of the key diagnostic criteria for the disorder is that the patient’s symptoms are severe enough to interfere with his or her ability to function in day-to-day life.

During a manic period, a person may miss work because they are too busy pursuing other activities they deem to be more important, or because they cannot focus on the task at hand. During a depressive episode, the patient may simply be too lethargic to get out of bed or fail to see the point in continuing to work.

10. FatigueType: Depressive

Contrary to manic symptoms, individuals suffering from a depressive episode will often experience extreme tiredness and fatigue. Wanting to go to bed, staying in bed late, and an overall lack of motivation throughout the day are all signs of bipolar disorder. These symptoms are one of the clearest examples of the day-to-night dichotomy between mania and depression.

In addition to physical fatigue, patients often feel mentally “bogged down” during a depressive episode, despite the fact that they are getting ample sleep. Mental sluggishness replaces energetic goal-oriented euphoria, and patients suddenly lack the drive or desire to do the things that interest them.

11. Chronic Pain with No Known CauseType: Depressive

Individuals experiencing other symptoms on the list, along with chronic pain with no known cause, may be suffering from bipolar disorder. This pain can present itself throughout many parts of the body including, but not limited to, severe headaches. Muscle aches and generalized, nonspecific body aches can also occur.

In some cases, the pain has a known cause, but is amplified and intensified. For example, a person with a mildly bruised knee may complain of unbearable throbbing pain that exceeds what would normally be expected from such an injury. Curiously, it seems that antidepressants offer the most effective relief from this type of pain.
